I've asked versions of this question before, but I'm actually looking to get a fairly comprehensive list written up. What fighters can make the claim to never losing at their prime weights, or only experiencing one loss and or a circumstantial one (DQ, Broken Bone TKO, ETC) Michael Spink's was unbeaten at LHW. 25-0. Micheal Moorer at LHW. 21-0, all knockouts. Wasn't Henry Armstrong unbeaten at his prime weight? Rocky Marciano at heavyweight, of course. 49-0. Holyfield at cruiseweight. 17-0. Vassily Jirov at Cruiserweight. 31-1. Roy Jones at middleweight and super middleweight. 32-0. I think Bob Foster may of been undefeated at light heavyweight. Currently, Joe Calzaghe at super middleweight through light heavyweight. 45-0.
Felix Trinidad at junior welterweight through junior middleweight, 38-0. Shane Mosely at lightweight. 31-0-0 Floyd Mayweather at lightweight through junior middleweight (Catchweight?) 39-0
Robinson at 147 Trinidad at 147 Gomez at 122 Spinks at 175 Marciano at heavy Lopez at 105 Pryor at 140 Arguello at 130 Benitez at 140 Holyfield at cruiser Morales at 122 Jones at 168 Calzaghe at 168 Mayweather at 130 Whitaker had the atrocious decision to Ramirez at 135, but that's it You can argue that 160 was James Toney's best weight, and that 135 was JC Chavez's best weight as well. Oh yeah, technically Svenn Ottke was never beaten at 168 as well.
Morales - 122 Robinson - 147 Chavez - 130 & 135 (He had a greater championship reign at 130 with 9 defences but probably peaked as a fighter at 135 vs Rosario)
With Foster at 176 and Mina at 180 odd i entirely disagree on this one Suze. IF anyone ever beat him at 175 This content is protected
I've heard the Mina decision was a terrible one where the rounds were actually lengthened or shortened accordingly to help Mina.
Interesting stuff. The bout was deffo not fought at 175 too. To the best of my knowledge Foster was never beaten at 175. I truly don't think he would have made 175 vs Mustafa.
